Hi, I don't know what this is supposed to do, but I get pretty bad migraines and loading the page made me feel extremely strange almost immediately so I closed it. I would check to make sure this can't trigger migraines or seizures. Maybe it's just me, but also, please double check.

Its supposed to show you how big of a radius your eye can focus on at a time, as we age the radius shrinks. Edit: seems like there isn't enough research to suggest the latter. Apologies

I don't know why you got downvoted. This seems like a very useful contribution.

  I also don’t think it is downvote worthy. The first part of the comment is very valuable. “I looked at it and it made me feel extremely strange almost immediately“. That is very good to know. The second bit I’m less sure about. What do they mean by “check to make sure this can't trigger migraines or seizures”? Like what check are they expecting? Literature research? Or experiments? The word “check” makes it sound as if they think this is some easy to do thung, like how you could “double check” the spelling of a word using a dictionary.

    I interpreted it loosely, as "be aware of the possibility, and stop looking at it at the first signs of issues".

      That seems to me to be a VERY generous interpretation of: > I would check to make sure this can't trigger migraines or seizures. Maybe it's just me, but also, please double check.

Interesting, I wonder.. have you ever tried a VR headset? Does that cause you migraines as well? or maybe any other discomfort that'd prevent you from using it?

  Not op but, VR is no problem, but this microsoft ar/mr glasses gave me an instant crazy headache in places I did not even know I had matter (back of the head), apparently thats the visual processing part of your brain. Terrible experience that lasted an hour or so.

I don't usually have headache migraines but do have strong visual auras from time to time. Looking at this it first looked fun: "whoa, that's cool, this fovea thing is really smaller than I imagined" After a minute or so playing around I closed the window and then I noticed a form of retina persistence that looked eerily similar to an onset of a visual aura, as well as some faint but clear ear ringing, both typical symptoms of the migraines I experience. I immediately walked away from the computer and although dwindling it's still in effect 10min out.

  Yes. Occasional migraine sufferer with aura here. Don't look at this unless you want to spend the next 15 minutes worrying "am i getting an aura or not".

How would someone possibly “check” that? What method are you proposing?

  there are a lot of papers on this (some made by inducing seizures in people under lab conditions). The most seizure causing things you could display are simply bars or a grid with moving details, sizes, or alternating in colors. Basically if it gives you a headache to stare at or just has this sucky attention grabbing feel to it when you look at it its likely to cause seizures. I CBA to dig up the papers on this but there are a bunch if you want to really get into this.

    You should be arsed to dig it up because your parent comment is insinuating disbelief or sarcasm with quotation marks.

      Here is the study that came to mind: https://www.cell.com/current-biology/fulltext/S0960-9822(17)30406-2 https://www.cell.com/current-biology/fulltext/S0960-9822(17)... However as the above study iirc doesn't directly state that these patterns cause discomfort and doesn't contain any examples I suggest reading chapter 10 "Photosensitive Epilepsy and Visual Discomfort" of "hierarchies in neurology (1989)" on page 70-71 which proposes this AND contains an example you can look at yourself.

Yes, immediately felt weird and a bit uncomfortable. I can almost see, or kind of sense, all those parts moving in the image even though I can only see the movement clearly in the center. I can easily imagine getting a headache from watching that for a longer time.
